SPECIFICATION forming part of Letters Patent No. 465,356, dated December15, 1891.

Application filed September 21, 1891. Serial No..4i06,.330. (No model.)

To all whom, it may concern: v

Be it known that We, JEPTHA P. DAVIS and GEORGE B. HARWELL, citizens ofthe United States, residing atMansfield, in the county of Sebastian andState of Arkansas, have invented a new and useful Combined Bin andJSitter, of which the following is a specilicaion.

The invention relates to improvements in fionr bins and sifters.

The object of the present invention is to simplify and improve theconstruction of o ur bins and sitters, more especially the agitator andmeans for operating the same.

The invention consists in the construction and novel combination andarrangement of parts hereinafter more fully described, illustrated inthe accompanying drawings, and

p pointed out in the claims hereto appended.

- cordance With this invention.

In the accompanying drawings, Figure lis a side elevation of a binconstructed in ac- Fig; 2 is a vertical longitudinal sectional vieW.Fig. 3 is a detail perspective view of the agitator. Fig. et is asimilar View of the pinion.

Like numerals of reference designate corresponding parts in all thefigures of the drawings. Y

l designates a cylindrical bin or receptacle adapted to contain flour orsimilar material and provided at its lower end with a contracted portionor neck 2, and having its npper end closed by a removable cover 3. Thecontracted portion or neck 2 has jonrnaled Within its sides a shaft 4,carrying an agitator 5 and having at one end a pinion 6, Which mesheswith a master-Wheel 7, mounted on a stub-shaft 8 and provided with acrank-handle 9, by which the agitator is operated. A removable sieve 10is arranged snbjacent to the agitator and is adapted to have flourforced through its meshes by the said agitator. The sieve is provided atits edge with a ring 11, which rests upon a circumferential ribv 12 ofthe narrow portion orA neck 2, and preparatory to removing the sieve forcleaning or mending, or the like, the shaft 4 is removed, aud to effectthis the pinion is provided with a cylindrical portion 13, havingrgrooves 14 in its sides arranged to receive the ag-itator, whereby theagitator is rigidly secured to the shaft, and the shaft-is enabled to bewithdrawn to permit the removal of vboth the agitator and the sieve. Theagitator consists of two'strips 17, disposed at right angles to eachother and bent' into an ap-y proximately elliptical form and havingtheir ends provided with perforations 18, and secured to the collar 16by a Wire tie 19, arranged in a peripheral groove of the collar. Thestrips are lprovided intermediate their ends with registering openingsthrough which the shaft 4 passes, and the shaft 4t is provided With aflange 21, arranged adjacent to the inner strip.

The bin has its lower end or dischargeopening closed when not in use bya cap 22, hinged to one side of the neck 2 and engaged by a clasp 23 atthe opposite side of the neck. g

The master-Wheel is an internal gear 'and is provided with teeth on theinner face of va circumferential ange, and the pinion is arranged Withinthe Wheel 7. y

It will be seen that the bin is simple and inexpensive in construction,reliable in operation, and that the parts may be readily removedforcleaning or unending.
